Multi-serial port medical treatment gateway makes the transmission that the serial data in medical detecting Instrument flows to ethernet data stream become
It may.The Multi-serial port medical data can connect multiple medical detecting Instruments with RS232 serial ports, and serial data is selected
It selects and handles, the stream compression chemical conversion ethernet data stream of RS232 interface, at the data that can be carried out networking in this way
Reason, realizes the networking of serial data.
In specific implementation process, ICP/IP protocol is made of application layer, UDP layer, IP layers and data link layer.In order to
Transparent transmission is realized in the present invention is implemented, increases application process protocol layer --- serial ports layer.Serial ports layer by serial ports link layer and
Serial network layer is constituted.Multi-serial port medical treatment gateway parses RS232 data packets in serial ports layer building, and as TCP/IP nets
The data transmission of network application layer.Multi-serial port gateway is made of ICP/IP protocol conversion module and Multi-serial port transmitting-receiving control module, firmly
Part concrete structure is as shown in Figure 4.Protocol conversion module is a miniature Ethernet access module, by microcontroller (MCU), net
The outer 512KBSRAM chip Is S6lLV5128 of card interface chip, EEPROM 93C46, piece and auxiliary element are constituted.Microcontroller
It controls network card interface chip and carries out network communication, realize address resolution protocol (ARP), Internet Control Message Protocol
(ICMP), the parsing of the agreements such as IP agreement, User Datagram Protocol (UDP) and package.Ethernet is sent to the serial ports of buffering area
Frame is encapsulated in UDP packets, and is transmitted to IP layers；Meanwhile receiving ethernet data frame and unpacking layer by layer upwards, the number of plies is applied in separation
According to then the dissection process of data transfers to Multi-serial port sending module to complete, and realization RS232 serial ports stream is saturating with ethernet port stream
Bright conversion.
The Multi-serial port control module obtains the string on medical detecting Instrument using the interrupt mechanism priority of microcontroller
Mouth data frame；Or the Multi-serial port control module gives response to obtain medical detection using polling mode to each substring mouth
Serial data frame on instrument.What Multi-serial port control module realized multiple RS232 serial datas streams transmits/receives control, including micro-control
The elements such as device processed, serial port extended chip (GM8123), MAX232.Microcontroller controls GM8123 and completes Multi-serial port data transmit-receive,
Multiple serial ports source datas are received, Ethernet is written after encapsulation and sends buffering area packing transmission；Meanwhile receiving Ethernet application layer
Data parse and are sent to measuring and controlling equipment.It is indifferent to the specific meaning of communication data, and only responsible reception/transmission, encapsulates/tear open
Serial ports frame is sealed, general-purpose interface is provided.In hardware environment used by Fig. 4, on the basis of there are 2 UART in the microcontroller, adopt
With GM8123, system can provide 2 groups (UARTO, UARTl) totally 4 serial ports (COM1, COM2, C0M3, COM4), utilize two-stage
Two priority classes UARTO is nested with the interrupt requests of UARTl and permission.Inside the interruption routine of UARTO, pass through inquiry mode
Determine which substring mouth is data source be.When two groups of serial ports have request of data simultaneously, first, the interrupt mechanism of MCU judges to interrupt
The priority of request, the interrupt requests preferential answering high to priority.System distributes priority：UART0 is 2, UARTl 1,
That is the interrupt requests of MCU preferential answerings UART0.It is right by polling mode when there is request of data in 3 rims of the mouth of UARTO simultaneously

Source；The starting boundary of frame head, postamble as a serial ports frame；Data portion is the original data stream from serial ports.Equally, network interface
Transmission data will also have consistent frame format, as shown in Figure 6.Obviously, serial data frame is the protocol data progress as UDP layer
Transmission.Multi-serial port medical treatment gateway realizes that the data conversion between multiple serial ports and a network interface, serial ports link layer complete serial ports number
According to transmission-receiving function, a part of the serial network layer as TCP/IP application layers realizes the encapsulation of serial ports frame.Transmission is into protocol stack
Process, as shown in fig. 7, it enters the encapsulation process schematic diagram of Ethernet protocol stack for serial data frame, reception is protocol stack
Process, the difference is that transmitting/receiving processing to data.
The data conversion of Multi-serial port to network interface is transmitted：Serial ports link layer receives the data from medical treatment detection device, gives
Serial network layer, this layer complete the encapsulation of serial data frame and are put into the transmission buffering area of Ethernet.The UDP as defined in the system is beaten
The packet time to or when having had 4 serial data frames, play UDP packets, and successively send down, it is complete until data are served physical medium
At the transmission of bit stream.
The protocol conversion module is packaged time threshold according to pre-set UDP or serial data frame threshold value carries out UDP
It is packaged, and ethernet data stream is formed according to ethernet data frame encapsulation process.In order to once transmit data more as possible, it is
System has made strict difinition to data length：The data segment maximum length of serial data frame is 300 bytes；Network interface sends the number of frame
At most allow 4 serial data frames according to section.Meanwhile also to meet requirement of the concrete application to real-time：Each serial ports is advised
The fixed longest response time.Time then, in spite of having received：300 bytes will be packaged serial data, and
It puts people's Ethernet and sends buffering area；Meanwhile in order to avoid system reaches 4 due to waiting for Ethernet to send buffering area serial ports frame number,
And cause serial data that cannot send in real time, it is desirable that an ethernet communication to be carried out within the regular hour, without waiting for 4
Serial ports frame is here to be just packaged transmission.System can guarantee concrete application to real-time the dual regulation of data capacity and time
It is required that and can once transmit data much more as possible, reduce since temporal " sky etc. " causes the possibility of system real time difference
Property.The function that 4 serial ports are completed in serial ports layer is identical, only by taking COMl as an example, provides data flow on serial ports layer, such as Fig. 8 institutes
Show.Fig. 9 illustrates that Multi-serial port data frame waits for the process for being packaged transmission.Network interface data to the data flow of Multi-serial port, be to
The process that the data frame of too Ethernet link layer successively unpacks upwards.As shown in Figure 10, the ethernet frame that will be received, removes every layer successively
Protocol header decomposite application layer data, then with 0x24 and OxOa be that boundary detaches, according to the value of serial port field, information sent out
It is sent to corresponding equipment, completes scheduled control.
It should be noted that the data communication module is WIFI module, ethernet data stream is sent to WIFI patterns
Ethernet data stream is sent to medical data management center by access point by access point；Or the data communication module is short
